STORAGE
WARNING:
Stop engine and allow to
cool, and secure the unit before storing or
transporting in a vehicle. Store unit and fuel
in an area where fuel vapors cannot reach
sparks or open flames from water heaters,
electric motors or switches, furnaces, etc.
Store unit with all guards in place. Position so
that any sharp object cannot accidentally
cause injury to passersby. Store the unit out
of reach of children.
S
Before storing, drain all fuel from the
unit. Start engine and allow to run until it
stops.
S
Clean the unit before storing. Pay particu-
lar attention to the air intake area, keeping
it free of debris. Use a mild detergent and
sponge to clean the plastic surfaces.
S
Do not store the unit or fuel in a closed area
where fuel vapors can reach sparks or an
open flame from hot water heaters, electric
motors or switches, furnaces, etc.

CAUTION
:
It is important to prevent gum de-
posits from forming in essential fuel system
parts such as the carbur etor, fuel filter, fuel
hose, or fuel tank during storage. Alcohol
blended fuels (called gasohol or using ethanol
or methanol) can attract moisture which leads
to fuel mixture separation and formation of
acids during storage. Acidic gas can damage
the engine.
